Super-Substances?

[Supreme]

I was wondering what kind of imaginary substances/materials do people use in their games to accomplish various comic book effects. For a Marvel Age campaign, I created "Isotope X" which is actually a space-born isotope of Lawrencium (atomic number 100, IIRC, which sounds so cool). Iso X is actually somewhat stable, but the nuclei do occassionally shift to lower energy states. However, in the case if Iso X, instead of releasing radiation is releases the "X-Effect" which amounts to localized disturbances in the laws of physics. The most common effect of this is to create super-powers. Some scientists have tried to provoke the X-Effect out of samples of Iso X, but due to its inherently unpredictable nature results are never consistent. Occassionally Iso X accidents have caused super-substances to come into being. Such substances are always unreproducable (inpenetrable shields and all that).

Instead of "super substances", how about "miracle materials":

Ballisdex. The infamous "bulletproof spandex" that so many superhero armored costumes seem to be made of. Difficult and expensive to manufacture, the material has "chainlinked molecular bonds" (comic pseudoscience) which allows the energy of impacts to be dispersed throughout the material rather than staying at the point of impact;

I like. There's always got to be something. I think the fact that bulletproof supers should have their costumes shredded everytime they get shot has probably contributed more to the anti-tights sentiment of the current era than anything else. I guess that particular can of worms has been opened and no one knows how to get it closed. I've seen virtually all comics and games in recent times have to go into often tedious explanations for why their characters aren't perpetual super-nudists. I think Byrne's "Man of Steel" probably did the best explanation thus far.
